Tuesday 12/2
Completed captions for supplemental images to accompany the completed individual growth summary. Populations that had no survivors after one year were excluded from the daily growth rate and average net growth. Brent showed me how to run an ANOVA test between each oyster population at different locations and oyster populations within a given site to test the significance of the average net growth difference. He refereed me Vassarstas to learn more about what an ANOVA test really means as well at to look at the PostDoc test to potentially do some further analysis on this data. Overall, It appears that Manchester had the most surviving individuals but Oyster Bay had the greatest daily growth rate and average net growth overall.

Monday 12/1
Completed measuring Oyster Bay oyster population on ImageJ from when trays were installed in location on 8/18/13 and the same population on 9/19/14. These measurements were converted and the difference between the later measurements and initial measurements was taken divided by the difference in days (426) to calculate the daily growth rate for each individual oyster which was then average to get that trays daily average growth rate so that we can compare growth rate among populations. Still need to finish captions for supplemental images and need to compile individual growth summary.

Tuesday 11/25
Completed measuring Fidalgo Bay oyster population on ImageJ from when trays were installed in location on 8/19/14 and the same population on 10/17/14. These measurements were converted and the difference between the later measurements and initial measurements was taken divided by the difference in days (426) to calculate the daily growth rate for each individual oyster which was then average to get that trays daily average growth rate so that we can compare growth rate among populations. Began setting up images and google excel sheet for Oyster Bay population for the same growth rate measurements.

Monday 11/24
Completed measuring Manchester oyster population on ImageJ from when trays were installed in location on 8/28/14 and the same population on 10/24/14. These measurements were converted and the difference between the later measurements and initial measurements was taken divided by the difference in days (428) to calculate the daily growth rate for each individual oyster which was then average to get that trays daily average growth rate so that we can compare growth rate among populations. Began setting up images and google excel sheet for Fidalgo Bay population for the same growth rate measurements.

Continued measuring Manchester oyster population on ImageJ from when trays were installed in location on 8/28/14 and the same population on 10/24/14. These measurements were converted and the difference between the later measurements and initial measurements was taken divided by the difference in days (428) to calculate the daily growth rate for each individual oyster which was then average to get that trays daily average growth rate so that we can compare growth rate among populations.

Monday 11/17
Completed measuring oysters for size at mortality measurements which is located on google drive. No statistical analysis has been completed on this data sheet yet.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Monday 11/10
Installed ImageJ on my personal computer and completed ImageJ analysis of Oyster Bay oysters. Jake has gone through Manchester, Fidalgo, and Oyster Bay samples and converted measurements for further statistical analysis.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Friday 11/7
Completed ImageJ data collection on Fidalgo Bay Oysters.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Tuesday 11/4
Continued ImageJ data collection on Fidalgo Bay Oysters.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Monday 11/3
Completed ImageJ data collection on Manchester bay oysters and started ImageJ data collection on Fidalgo Bay oysters. Both are compiled on spreadsheets on Google Doc shared with Jake that are going to be converted and used for R analysis later on. I continued to measure shell size at mortality from sample 1H 5-8 on 5/23/14 and completed those oysters specifically and still have two gallon sized ziplock bags left to process.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Friday 10/31
Learned how to use ImageJ from Jake and started taking measurements from trays at Manchester. A Google Doc was created that measurements are being entered into and shared between Jake and I. Today I got through 6 trays so Monday I will need to finish the 6 other trays. Data entered includes sample, area, mean, min, max, angle, and length which were formulated by ImageJ. The first tray I measured was hard to identify the beginning and end of some oysters so I took a picture and circled the oysters that were not measured. Otherwise all other pictures seemed fine but the oysters appear to have stained some of the tiles so finding a definite end to the oyster shell is slightly difficult. Overall, majority of the oysters are measurable.

Tuesday 10/28
Empty oyster shells from Jake's project this summer were kept, some frozen. Shell width from the umbo to the loargest diameter of the shell were measured using calipers. Data was enter into size at mortality google doc which included date, site, tray, sample, and size.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Monday 10/27
Data from Jake's field notebook of year 1 sampling from Oyster Bay, Fidalgo Bay, Manchester, and Dahob were entered into a google doc including the date, site, tray, sample, size and weight for further analysis on R.

-Read through QIAGEN DNeasy Handbook and Commercial Guidelines for Genomic DNA Extraction
-Summarized Protocols for both Procedures
QIAGEN DNeasy Protocol: Purification of Total DNA from Animal Tissues (Spin-Column Protocol)
Preparation
-Make sure there is no precipitate in Buffer AL and ATL, if so warm to 56 °C to dissolve
-Add appropriate amount of ethanol (96-100%) to Buffer AW1 and AW2 indicated on bottles
-Preheat thermomixer to 56 °C
